Letters Patent No. 102,473, dated May 3, 1870; nntellated April 20,1870.

IMPROVED FASTENER I OR BEDSTEADS, TABLES, 8m.

The Schedule referred to in these Letters Patent and making part of then'amo Be it known that I, J AMES M, BAIRD, of Wheeling, in the county ofOhio and State of lVest Virginia, have invented a new and ImprovedFastener, of' which the following is a specification.

The nature of my invention consists in forming, in` or on each of thearticles to be fastened together, or in and on plates to be attachedbyserews or otherwise to the articles, apointed beveled projection, 'thedis,

tance ofthe projection from the body of the article or plate being equalto its thickness at its base, and its bevel, of any desired angle, beingfrom its point toward and down to the body of the article or plate, andas far down the edge of the projection and body of article or plate asthe `selected angle produces it.

Thus constructed, the projection forms, with the articleor plate, apointed, beveled, projecting notch. And, when two of said projections,thus provided on articles or' plates, arc mated or matched together,which is done by bringing and placing `the bevel of one with that of'the other, they form and make the fastener which I claim as myinvention, ,whereby articles of manufacture for whichl it may besuitable, such as the various parts of bedsteads, tables, wardrobes,boxes, bureaus, house and other frames, Sto., may be firmly fastenedtogether.

When plates are used I provide opposite recesses in each one, in which Iplace a sliding key, which, when adjusted, prevents one projection frombeing with-l drawn from the otheri 'But this arrangement is notnecessary to complete the fastener, and may be used or not.

-the desire-d form of the thing to be fastened.

It can be either cast on, out in, or attached tothe article, as the casemay require or suggest, and each by the usual methods of doing suchwork.

.Description of the Accompanying Drawings.

Figures 1 and 2 represent one side of the projection as formed .uponarticles or plates.

Figures 3 and 4, the other side of the same.

Figure 5, two of the projections formed upon plates mated or matchedtogether, or complete fastener; and in this casethe plates are fastened,one to the other,

at a right angle; and in which the articles or plates having theprojections formed on them are marked by the letter A; the pointedbeveled projection by the letter B; the bevel of projection by theletter C; the

base of projection by letter D; the recesses `by the` letter F; key byG; and the mated or matched projections or complete fastener by letterH.

What I claim as my invention, and desire to secure by Letters Patent,is-

'lhe construction of .a fastener,v consisting ofthe plates or-artioles AA, with the projections B B, bevels C C, with or withoutthe recesses F,and key G, all

arranged as and for the purpose described. j
